Description

High-carbon molecular oil electric heating unit with modular structure

Technical Field

The utility model belongs to electric water heater or electric boiler field, specifically speaking relates to a modular structure's high carbon molecule oil electricity heat supply unit.

Background

At present, heating equipment can be classified into an electric boiler, a gas boiler, an oil boiler, a coal boiler, and the like according to the difference of fuels. In comparison, coal-fired boilers are adopted for heating mostly due to low use cost of the coal, and the pollution of the coal is high, so that the coal-fired boilers gradually quit the market at present. The natural gas leakage causes boiler explosion every year, so the electric heating equipment is safer, energy-saving and environment-friendly, no gas emission exists, and the electric heating equipment conforms to the national environment protection requirements, so the national strong support is obtained, the policy of changing coal into electricity is continuously carried out in recent years, the coal boiler with low efficiency and poor safety is disassembled and changed into the electric boiler or the related electric heating equipment, although the electric boiler develops for years, the advantages are outstanding, the production cost is easy to realize the heating purpose quickly, meanwhile, the use cost of users is greatly reduced by the existing national electricity price policy, so that electric boiler manufacturers are more and more, the industrial competition is formed, the continuous updating and improvement of electric boiler products are promoted, and the electric boiler products are developed towards lower cost, high efficiency and intellectualization. On the other hand, the common mode of directly heating water by electricity has more problems, such as scaling on the surface of a heating pipe, short service life, higher maintenance cost per year and needing major repair after several years, so the later maintenance cost is high. The heat energy conversion equipment which uses electric power as energy and uses heat transfer oil as a heat conducting medium well solves the problems caused by equipment which directly heats water by common electricity, and simultaneously can obtain high temperature under normal pressure and has wide temperature range, so that the system safety is high and more stable, the water treatment equipment is saved, and the system efficiency is improved. In addition, a novel heat transfer medium is prepared by selecting high-carbon molecular heating oil with high heat conductivity, namely, a special additive is added into the heat transfer oil, and the heat transfer effect of equipment can be improved and the overheating of oil products can be avoided by utilizing the heat transfer medium.

Although the oil-electric water heater using heat carrier oil as a heat medium for heat exchange solves the problems of the maximum energy efficiency and the service life of the existing electric water heater, the oil-electric water heater in the prior art has some defects, the electric water heater in the heat carrier heat exchange form or the electric boiler in the market has more series because each specification is an integral heating system, and the adopted heating mode is that a closed cavity is directly heated and the heat medium is not circulated, so the service lives of an oil product and a heating rod are directly influenced, and the heat exchange speed is slower; for example, patent 200610122514X "high carbon molecule heating oil energy-saving electric water heater", and utility model patent: 2018214065575 high carbon molecule heating oil electric water heater with internal and external spiral heat exchange structure, 2018218506153 high carbon molecule heating oil heat supply unit and the like, and the problems are all caused because the integral production of a heating system is required to be carried out for each power specification while a heating medium circulation mode is not adopted. In addition, although some patents use a circulating oil pump, there are limitations, for example, in 2017214165579, "an organic heat carrier boiler based on variable frequency electromagnetic energy heating" uses an oil pump to circulate the heat medium in the heater, but the patent only uses the oil pump as the heating of the heat carrier oil to heat other liquid after heat exchange, and such a structure does not exert the maximum efficiency of the heater due to insufficient heat exchange area, and thus has limitations. Or the utility model patent: 201721147305A high-frequency quantum organic heat carrier boiler has complex structure and low safety performance, the gasification pressure of heating oil is easy to increase instantly when the heating oil contacts with water, the heat preservation effect by gas is not ideal, and the structure of the shrinkage and expansion device is not stable. The invention also discloses a method for preparing the following components: 201510541103.3 the electric heating heat conduction oil furnace system has complex structure and low integration level.

Therefore, the electric boiler for heat exchange of integral heat carrier oil in the prior art has certain defects, and needs more in-place electric heating equipment which has a reasonable structure, can be produced in batch and can evacuate water stored in the electric boiler.
